Specification of Letters Patent.

Patented Jan. 28, 1919.

Application filed April 18, 1917. Serial No. 162,849.

To all whom it may concern:

Be it known that I, RALPH PETERSON,

a subject of the King of Great Britain, residing in Cypress River, Manitoba, Dominion of Canada, have invented a new and Improved Tractor, of which the following is a full, clear, and exact description.

My invention has for its object to provide a tractor having a drive wheel within which a motor is disposed, the fuel for the motor as well as the motor-controlling means, being led through the hubs of the drive wheel.

Another object of the invention is to provide a radiator for cooling the water in the water jacket, and having a fan which is rotated by a turbine driven by the exhaust. from the motor.

Additional objects of the invention will' appear in the following specification, in which .the preferred form of the invention is disclosed.

In the drawings similar reference characters denote similar parts in all the views, in Which- Figure 1 is a side sectional elevation of my tractor looking at one side thereof;

Fig. 2 is a sectional plan view of Fig. 1;

Fig. 3 is a side elevation of the tractor looking from the other side;

' Fig. 4 is a sectional view on the line 44 of Fig. 1;

Fig. 5 1s a front elevation of the radiator shown on the tractor in Figs. 1. 2 and 3; and

Fi 6 is a sectional view on the line 6-6 of Fig. 1, parts being broken away to illustrate the construction.

By referring to the drawings, it will be seen that a drive wheel 10 is provided which has hubs 11 mounted for rotating around the inwardly extending portions 12 of the main frame 13. The hubs 11 preferably rotate on ball bearings 14. Disposed within the main frame 13 and secured to the inwardly extending portions 12 of the main ing supported by the auxiliary frame 15.

The shaft 17 of the internal combustion engine is provided with the usual cranks 18 which are connected with pistons 19 by means of piston rods 20. The shaft 17 extends outwardly through an opening 21 in one of the inwardly extending frame 'members 12 to a point beyond the main frame 13. This motor shaft 17 is disposed in a hollow shaft 22 provided with bearing portions' 23 and 24 which are engaged by bearings balls 25 which separate the hollow shaft 22 from bearing members on the inwardly extending frame portions 12. Secured to the hollow shaft 22 beyond the main frame 13 there is a clutch member 26 which is adapted to be engaged by clutch members 27. These clutch members 27 are connected by means of links 30 to a collar 28 keyed to the motor shaft 17 and held yieldingly outwardly by means of a spring 29 disposed around the motor shaft 17, the construction being such that when the collar 28 is moved inwardly it will press the clutch member 27 outwardly and against the clutch member 26 by means of the links 30. Mounted on the hollow shaft 22 there is a gear 31 which meshes with a gear 32 secured to a shaft 33 journaled in bearings in the. auxiliary frame 15, there being another gear 34 which is mounted on this shaft 33, this gear 34 meshing with a gear-35 mounted on a shaft 36 journaled in bearings in the auxiliary frame 15, there being also another gear 37 secured to the shaft 36, this gear 37 meshing with inner teeth 38 on the drive wheel 10. It will therefore be seen that when the clutch members 27 operatively engage the clutch member 26. the drive wheel 10 will be rotated when the engine is operated.

The collar 28 keyed to the shaft 17 is moved inwardly or outwardly as may be desired by means of a lever 39 which is connected with a hand lever 40 at the operators seat 41. this hand lever 40 being connected with a crank 42 On a shaft 43 by means of a link 44, there being another crank 45 on the shaft 43 which is connected with the lever 39 by means of a link 46. Mounted on the main frame 13, preferably at the rear of the drive wheel 10, there is a gasolene tank 47. a pipe 48 leading from this tank 47, the said pipe 48 passing inwardly through an opening 49 in the other inwardly extending frame member 12. The pipe 48 is connected with a carbureter 50 in the customary manner, a manifold 51 leading from the carbureter to the motor valves.

, A sprocket chain connects a sprocket wheel on the motor shaft with a sprocket wheel secured to a shaft on a magneto 55. A gear 52 on the motor shaft meshes with a gear 54 on a valve shaft 60, the valve shaft having cams 61 to which valve-operatlng means is connected. The carbureter 50 is controlled by means of a link 63 which passes outwardly through an openin 49 m the inwardly extending frame mem or 12. The outer end 64 of the link 63 is articulated to an arm of a lever 65, the lever 65 being fulcrumed at 66 to a bracket secured to the frame 13, and the other arm of the lever 65 being articulated to a link 67 which is articulated at 68 to a crank 69 on a shaft 70 journaled in hearings in the main frame 13. A hand lever 71 disposed at the seat 41 is connected with the shaft 7 O by means of a link 72 and a crank 7 3 secured. to the shaft 70. With this con truction it is possible for the driver of the tractor to sit on the seat 41 with his feet on the foot rest 74, and control the tractor by means of the lever 71 which is connected with the carbureter by the means described, and the lever 41 which is connected with the clutch by the means already described. The steering wheel 75 is disposed under the main frame 13 adjacent the seat 41, this steering wheel 7 5 being mounted on frame members 76 from which extends upwardly a stud 77 journaled in a bearing 78 on the main frame gearing 79 connecting a hand wheel 80 with the stud 77 so that the vertical axis of the steering wheel 75 may be rotated as desired.

Mounted preferably at the front of the main frame 13 there is a radiator 81 having a fan 82 for cooling pur oses, this fan 82 be ing mounted on a sha t 83 journaled in a bearing 84 in the radiator 81. There is also a turbine 85 mounted on the shaft 83 for rotating the fan 82 by means of the shaft 83. An exhaust pipe '86 from the motor passes through an opening 49, and to the turbine 85, so that the exhaust ases will engage the turbine blades, by wh1ch means the fan 82 will be rotated. There is a water acket 87 around the motor, and from the water jacket 87 the heated water asses through a pipe 88 to the top of the ra iator 81 at 89, the water which has been cooled by the radiator passing through the pipe 90 to the rotary pump 91, which forces the water mto the water jacket 87. These pipes 88 and 90 pass through the opening 49 in the inwardly extending frame member 12.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:
